\ MOWING MACHINE Application filed August 22, 1930. Serial No. 477,109.

This invention relates to certain new and useful improvements in mowing machines of the manually operated type embodying a forwardly positioned horizontal reciprocatingl cutter bar operatively engaged with one of the ground wheels, of the machine and having superposed upon the machine frame, an endless conveyor or gathering device operatively engaged with the other ground wheel of the machine for moving or displacing the cut grass and the like laterally of the path of travel of the machine into rows for later gathering.

A further object of the invention is to provide a mowing machine of the foregoing type wherein the conveying device for shifting the cut grass and the like laterally of the machine, may be manually operated while the machine is at rest.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

Figure 13 is a. detail sectional view showing one of the ground wheels and the separable gear connections between the Wheels and cutter bar.

Referring more in detail to the accompanying drawings, there is illustrated a mowing machine comprising a U-shaped frame as shown in Figure 1 having side bars 1 and 2 connected by a cross bar 3, the forward ends of the side bars 1 and 2 being attached to a cross bar l as shown in Figure 3 and extending forwardly of the cross bar as illustrated. The forward ends of the side bars 1 support a stationary horizontal cutter bar 5 with which is superposed reciprocating cutter bar 6 is associated and to he operated by devices presently to be described.

A shaft 7 has the opposite end portions 8 and 9 thereof journalled in the side frame bars 1 and 2 as at 8 and 9 and extend outwardly of the frame bars to support freely mounted ground wheels 10 and 11.

A handle structure is supported on the shaft 7 and cross-bar 3 of the frame as shown in Figures l to 3 and comprises a tubular handle 12 carrying a breast plate 13 at its Vrear end while the forward end thereof is bearing 17 carried by the cross-bar 3 of the frame and held in adjusted positions by the set screw 18.

During forward movement of the machine, the ground wheel ll operates the forwardly positioned horizontal cutter bar and the operation thereof may be discontinued while the machine is still forwardly propelled by disengaging the pinion 26 from the driving gear 25. The ground wheel l0 effects operation of the endless conveyor While the direction of movement thereof is controlled by the gears 62 and 63 shown in Figures l() and ll. During forward movement of the machine, the cross arm 23 moves upon its pivotal mounting 24 and while the machine is at rest, the cross arm 23 may be manually operated to effect movement of the crank shaft 7 and endless conveyor so that the machine may be moved into proximity of a pile for lateral discharge or displacement of cut grass or the like.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, and while there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
